HOW TO SOLVE VENEER BUCKLE IN THE WORKSHOP
We purchase dried veneer and do our own laminating. Sometimes the veneer is not flat but has what we call buckle or wavy spots. Can you tell us what is causing them? We’re especially interested if it is the way we handle the veneer? A. Veneer buckle (also called warp) is a general distortion of the sheet of veneer so that the sheet is not flat. The most important causes of veneer buckles are due to tension wood, irregular grain, and non-uniform drying. Tension wood: Also called growth stress, this occurs naturally as the tree is growing. These special wood cells that create tension wood are formed as the tree is responding to an outside force (wind, sunlight competition, a tree leaning against another, or a heavy branch, for example). Large growth stresses undoubtedly contribute to end splits in freshly harvested logs. Heating the veneer log, bolt or flitch before cutting can aggravate these splits. Unfortunately, the tension wood stresses in the tree are not always uniform...
